Running along the coast of Karnataka from Udupi through Mangalore to Kerala, UTPL is a 90.3-km toll road, part of NH66. The corridor and its three toll plazas witness a significant amount of traffic because it offers connectivity to the refinery at Mangalore.

Part of the North-South Corridor from Kanyakumari to Srinagar, this road is a major link between Bengaluru and Chennai, and other districts in Tamil Nadu. This 24.365-km section of NH7 runs between Bengaluru Urban in Karnataka and Krishnagiri in Tamil Nadu, along the key settlements of HSR Layout, BTM Layout, Silk Board Colony, Bommanahalli, and Electronic City.
